Answer first
A simple rule: cleanse, dry, then apply the thinnest, most watery leave-on first and let each layer settle before the next. In practice, many people use their minoxidil topical alone at one time of day and Folli-Flux or Folli-Care at another, rather than layering everything at once. Ask your consultant for your plan.
Thin to thick
Watery serums before gels; styling products go on the hair last.
Separate the strong ones
Keep minoxidil topicals on their own slot to reduce irritation.
Questions
How long between layers?
Wait until the scalp feels dry.
Can I mix them in my hand?
No, apply separately.
